Rush Machinery will showcase a balancing machine and a wheel truing and dressing machine at the 2022 International Manufacturing Technology Show (IMTS), being held at Chicago’s McCormick Place from September 12–17. Rush Machinery can be found in Booth 237233.
The BMT-200TS Balancing Machine is designed for the balancing of mounted grinding wheels, wheel packs, and cutting tools. The features of this benchtop unit include self-calibration, automatic clamping and positioning, a clear safety cover, and a graphical user interface running on included laptop PC. There is also an onboard memory with 240 data sets (expandable as an option).
Balancing methods for the BMT-200TS are GRAMM with set screws at fixed arbor positions axially or radially; Split angle with balancing rings; Fixed position with set screws; Drilling; and Milling.
The FC-350EX Wheel Truing and Dressing Machine is designed for truing and dressing flats, angles, and radii on diamond and CBN single wheels and multiple wheel packs. The FC-350EX is simple to operate, highly accurate, and cost-effective. Its features include a full enclosure for added safety, PLC controls for automatic precision infeed, oscillation, and pivoting of the truing wheel axis.
The machine also comes installed with RushVision with Autoview, a software designed to make truing and dressing easy and customizable. RushVision aids in high precision, high tolerance work, and truing complex forms and radii up to 2” (50mm). The software includes drawing templates for most common wheel shapes and allows users to import from CAD via USB port or networked PC.
The company's machines include truing and dressing Diamond/CBN wheels; cutting off carbide/HSS rods and tools; cutting, prepointing, and chamfering carbide/HSS rods; chamfering carbide/HSS rods; balancing wheels and tools; grinding PCD tools; filtering grinding oil; and sharpening drills and tools.
Related Glossary Terms
- arbor
arbor
Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.
- chamfering
chamfering
Machining a bevel on a workpiece or tool; improves a tool’s entrance into the cut.
- computer-aided design ( CAD)
computer-aided design ( CAD)
Product-design functions performed with the help of computers and special software.
- cubic boron nitride ( CBN)
cubic boron nitride ( CBN)
Crystal manufactured from boron nitride under high pressure and temperature. Used to cut hard-to-machine ferrous and nickel-base materials up to 70 HRC. Second hardest material after diamond. See superabrasive tools.
- dressing
dressing
Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- milling
milling
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- polycrystalline diamond ( PCD)
polycrystalline diamond ( PCD)
Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.
- tolerance
tolerance
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
- truing
truing
Using a diamond or other dressing tool to ensure that a grinding wheel is round and concentric and will not vibrate at required speeds. Weights also are used to balance the wheel. Also performed to impart a contour to the wheel’s face. See dressing.
